Nexus 4 stock shortage down to 'huge demand', LG explains

The LG-built Nexus 4 went on sale in mid-November, but sold out in half an hour. It was briefly back in stock on Tuesday, but by Wednesday morning the 8GB version was already out of stock again. I contacted LG with a few inventory-related questions.
